如何从C#调用非托管C ++类DLL?
You may want to create a managed C++ wrapper for that class, compile it with /clr (common language runtime support) and then you can use it in C#. You may also want to look at PInvoke.
The CLR doesn't support directly using native C++ classes, it prefers static methods to call via PInvoke or COM interfaces to use via COM interop. So some kind of C++ wrapper is required.
您需要使用P / Invoke及其封送处理
For example like this :
public unsafe class CppFunctionImport
{
[DllImport("ImageProcessingCpp.dll", EntryPoint = "PerformMovingAverage", ExactSpelling = true, CharSet = CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]//!-!
public static extern void PerformMovingAverage
(
ref byte *image,
int width,
int height,
int stride,
int kernelSize
);
}
Create your small wrapper, import desired functions and call
